Thank, Manolis, it did address some concerns.

I think I even know what you did with the MF driver. You were able to get 50Hz out of this looks like horn? This is impressive. The boundaries-loaded horns sometimes allow doing away with the horn size and make even the 1/8 size to be operational. Might I ask you: what is the resonance frequency of your midbass driver loaded?

If I were you I would very certainly go for a slightly smaller midbass driver and a slightly smaller midbass throat. Let pretend that it would be 10” driver and 10” smaller throat. Then your midbass horn will go a feet taller – very manageable. As the benefit you might have:

1)    Ability to make the back chamber twice smaller.
2)    Removing the reflective corner from tweeter pass
3)    Pick a few dB of equalization at the bottom of midbass’ output

BTW, even as it is I would make the back chamber on the vertical horn not rectangular but circular…

Also in my own designs around the vertical-horizontal configuration I thought about the provision to add the “footprint extenders”. The point was that if I make the mouth larger then I get more dB. In any installed speaker one (or two) sides has room to have a lager horn. So, the idea was to add a “wing” to one side to make the asymmetrical large footprint. In some cases it might extend the loading to the wall and pick up 5Hz -10Hz, which always would be very welcoming. In some case you do not even to have the contact between the “wing” and the speaker and all that you need to have is an RTA and a heavy panel semi- horizontally positioned and sitting on the floor on 3 legs with individually adjustable height.

Might I ask you how do you fine the sound of the Anima? Anything that you like and anything that you would like to have to sound differently? Do you listen them “as is” or you use a help of some kind of complimentary LF devise? If yes, then what LF you feel works well with Anima? How heavy the upperbass horn? Did you detect any differences in sound and in midbass resonance frequency when you placed the upperbass not on the hard legs but on the spongy legs? How about a fat hairy carper – what difference it makes? What music do you listen?
